"To be honest, from the beginning of the war to the present, I am not satisfied with the performance of the Air Force, if it weren't for the big difference in the national strength of the two sides, we might have lost the war." Looking at the blue sea, Kesselring said to Raeder beside him.

"Although there are reasons to play away, our fighters are not as good as our opponents, especially in terms of speed and climb. There is already a gap between our aero engines and the British, and if we want to maneuver both horizontally and vertically, then in the end we will not be able to do anything. How so? This is a bit similar to the comprehensive protection and key protection mentioned by the navy, the former is a large protection area, but it cannot be prevented, while the latter although it sacrifices part of the performance, but it maintains the core cabin defense. Kesselring finished and looked at Raeder.

"There's also productivity and maintenance. What we need is as simple and convenient as possible to produce an aircraft rather than an advanced aircraft on paper, but with low uptime and difficult to produce. Our national strength is inferior to that of the other side, and the most important issue is how to use as few resources as possible to transform them into the strongest combat strength. I once saw a fighter jet from Messerschmidt at a new aircraft bid for the Air Force...... It's very small, but the structure is simple, and the speed and climb are good. Raeder thought for a moment and said..........

"You mean BF109? He is really good, although the horizontal maneuverability is a little worse, but the vertical maneuverability is very good, and the speed is very fast, and there is another problem that the range is relatively short, and there may be some gaps with our requirements. Of course, if you change to a better engine. This problem may be able to be solved to a certain extent, which is good as a front-line fighter. Kesselring said.

After some discussion between the two, the two sides reached a consensus on the following points. First of all, the main fighter type of the Air Force must be a moderate range, which can fly more than 900km with a 300-liter auxiliary fuel tank attached. This range was accurately calculated, and as a purely front-line aircraft of the Air Force, such a requirement was clearly sufficient. And as a naval aircraft of the Navy, Raeder and some technicians discussed and believed. The half section of the sea operation generally does not exceed 350 km or more, because the attack aircraft group needs reconnaissance aircraft to guide it. As the distance increases, the guidance efficiency decreases, after all, the blue patch on the sea is not like the ground where the position of the two sides can be judged according to the terrain, and the battleship is moving. It's slower, though. More importantly, if you want to let the planes on several aircraft carrier groups fly to a certain target at the same time, this kind of guidance will be more troublesome, and you will have to guard against the battle becoming a refueling tactic. Attacking 100 planes in one wave, and attacking 100 planes in four waves is not the same concept! Moreover, flying too long on the sea surface is easy to cause fatigue of personnel. Directly leads to a decrease in combat effectiveness ..........

Secondly, this is the result of the balance of aircraft performance, first of all, if an aircraft wants to climb fast, then the power-to-weight ratio is a very important parameter. Although the liquid-cooled engine has less frontal wind resistance, its power is lower than that of the air-cooled engine. If you want to climb fast, you have to lose weight. How to lose weight? In addition to the necessary weight of the fuselage, you can only use weapons and fuel to open the knife. But look at one 20mm cannon and two 13mm machine guns for fighters in the future. German designers simply couldn't bear to pick up a pencil to cut weapons again. So it can only be cut from the fuel load, and at present, the fuel volume of the new aircraft theoretically does not exceed 600L. If that's not enough, consider flying with a drop tank.

Actually. If you want to say that 600L of fuel is also a lot, a Japanese designer at the Luftwaffe headquarters once patted his chest and said that if I give me 600L of fuel, I can also make a fighter fly more than 1500 kilometers, which shocked the Germans, and they really wanted to see what kind of East and East this Japanese could build when he got to the ground. As a result, I was almost shocked when I saw it! The weight is quite light indeed. And the wing load is also small. That is, horizontal maneuvering would be very good. And the range can really meet the requirements of what he said. But when it comes to pros, that's it! And after seeing this aircraft, the German designers believe that more than ninety percent of pilots will refuse to use this aircraft! …………。

There is no self-enclosing mailbox. The members of the defensive armor were almost non-existent. The structural strength is somewhat worse. Although horizontal maneuvering is good, for example, the turning radius is relatively small. Hovering is also good. The climb can also be described as improvised. But the speed is just too sad. And the payload of this aircraft is small! Not even a 250kg bomb could be loaded, that is, it was a pure fighter with almost no weight for other functions. If you have to bring bombs, make do with two 60kg bombs to blow up the infantry. (If you are interested, you can check the performance gap between the 1941 egg and the BF109F2 and F190A4 of the same period. Of course, the author admits that a big reason for this is because the eggs are too sad for the engine, but the oversized wings do affect the speed. Although this aircraft can have a large range with a 500L fuel tank, it lacks a very slow cruise speed.

In addition to fighters, the German Navy also put forward new requirements for attack aircraft, and they hoped to develop a multi-role attack aircraft that could be used as both a dive bomber and a torpedo aircraft. Because in practice they found ...... After the simple torpedo machine uses up the two or so torpedoes prepared on the aircraft carrier, the rest can only be used as horizontal bombers, and the accuracy of horizontal bombing is generally not as good as dive bombing, and the huge bomb load of the torpedo plane is wasted in vain. Serious losses in the combat effectiveness of aircraft carriers were caused, and tactical flexibility was reduced. If a general-purpose aircraft can be built, then all these problems can be solved. Moreover, the Navy has also put forward the load requirements for a new generation of attack aircraft, that is, it must be able to carry 500kg bombs for large-angle dive bombing, and it can carry a torpedo for attack. At the same time, the cruising speed should be as fast as possible in order to keep up with the speed ......... the new fighters.

In order to be as fast as possible, the wingspan of the original bomber had to be controlled, and the landing gear had to be able to be tucked into the fuselage. At the same time, it is necessary to lose as much weight as possible. At the same time, it is necessary to control the frontal wind resistance of the aircraft. If nothing else, the historical JU87 will enter the combat sequence of the Luftwaffe. But the war ultimately affected the progress of this aircraft in service. Because this guy flies too slowly! The speed difference between the two and the escort aircraft makes it difficult for the two to form a formation. In addition to the Air Force's statement that it can be used as a battlefield support aircraft because of its strong bomb load, the Navy strongly demands that it design a dual-purpose attack aircraft.

(Historically, the Ju87 engine was really good, and the JuMO211 engine used in the Ju87D had 1400 to 1500 horsepower.) And it's also liquid-cooled. But the frontal wind resistance is too great, look at the big chin under the ju87 engine, there are two landing gears that can't be retracted, and a super large wingspan. By the way, there is also the weight of the ju87d. The author has never understood why the JU87D is so much heavier than the JU87B! The torpedo machine with no load and a book has a full load weight. Except for the load NB and attack power NB, there is no advantage-! ）

From the design requirements of the above two aircraft, it is not difficult to see that the Germans are pursuing aircraft performance advantages. And for the sake of this performance advantage, the range has been appropriately reduced. And it is intended to rely on sophisticated aircraft to directly pierce the opponent's air defense network. Rather than relying on numbers to saturate the opponent's defenses and then attack, because the German navy believed that it would be difficult for them to achieve numerical superiority in future wars. This is caused by the disparity in national strength, and there is no way to change it. Just like in the First World War, the Allies were .........at a disadvantage based solely on national strength.

By the way, in addition to these two aircraft, there is another aircraft that makes the German Navy very interested, and this aircraft is the twin-engine light fast bomber. Although they are both two engines, twin-engine aircraft also have sizes, for example, small twin-engine aircraft can only carry one torpedo, but relying on the lighter weight can obtain better flight performance. Larger twin-engine bombers, on the other hand, can carry two or more torpedoes, but their flight performance is very average. At one time, the top brass of the Luftwaffe was inclined to the latter aircraft, after all, they believed that their fighters could be absolutely trusted. However, after actual combat testing, they found that the fast bomber with the ability to penetrate the defense at high speed is an indispensable sword to cut through the opponent's defense. So the Germans also planned to build a fast bomber of this kind and equip the navy and air force at the same time. …。

"Our engines are also relatively backward, and the British are said to have a higher power-to-weight ratio and are equipped with a supercharged device to improve flight performance. We are still lagging behind in this area. And in addition to liquid-cooled engines, the development of air-cooled engines must also be strengthened, after all, air-cooled engines have stronger damage resistance and greater power. Raeder finally added this sentence to the document.........

Historically...... The Germans are indeed a little more skilled in liquid-cooled engines than air-cooled engines. Moreover, there are many liquid cooled aircraft in Germany, such as the DB601 and DB605 series of BF109, the Jumo211 series for bombers such as JU87, and the JuMO213 series for F190D and TA152 later. and another high-power liquid-cooled engine DB603 series and so on. The only one used in air-cooled engines is the BM801 series.

And this time, the reason why the Germans demanded to speed up the development of air-cooled engines was due to the poor damage resistance of fighters equipped with liquid-cooled engines in many battles. As long as the engine is hit, the plane will never come back! If it's on land, then you can save it, but what if you fall into the sea? So in order to keep the expensive pilots, the German Navy felt that some air-cooled engines were needed to improve the survival rate of the pilots.
